Abstract

fetched live from OpenAlex

This paper describes a real time vision system, allowing to localize faces in video sequences and to recognize their identity. These processes are based on combining techniques of image processing and neural network approach. The robustness of this system has been evaluated quantitatively on 8 video sequences. We have tested our model using the ORL database in order to compare performances with other systems. The system has also been implanted on electronic architectures based on dedicated chip ZISC and FPGA. We analyse the algorithm complexity and we present results of hardware implementations in terms of used resources and processing speed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
